Cov khoom siv yas sib txawv xav tau cov txheej txheem sib txawv yas vuam
Ib qho khoom lag luam yas yuav ua los ntawm ntau cov ntaub ntawv lossis cov khoom siv. Los ua ke cov khoom sib xyaw, kev kho tshuab fasteners, nplaum thiab vuam cov txheej txheem tuaj yeem siv tau. Ntawm peb txoj hauv kev koom nrog, txheej txheem vuam muaj cov txiaj ntsig zoo tshaj plaws, thiab muaj ntau yam ntaub ntawv vuam. Cov txheej txheem vuam sib txawv tuaj yeem siv raws li cov ntaub ntawv sib txawv, qhov loj me, thiab siv.
Mechanical fasteners, nplaum thiab vuam cov txheej txheem tuaj yeem sib koom ua ke ntawm ob lub tshuab ua tshuab. Cov neeg kho tshuab ua nrawm tuaj yeem txuas ob qho kev sib txuas, tab sis kev xau pov thawj ntawm kev sib koom tes yog qhov tsis zoo, thiab kev ntxhov siab hauv zos tseem tuaj yeem ua rau cov khoom siv polymer cais.
Cov nplaum tuaj yeem tuaj yeem muab cov khoom zoo thiab tsim cov koom ua ke nrog cov dej xau zoo ua haujlwm. Txawm li cas los xij, nplaum ua kom yooj yim los daws thiab maj mam kho. Nyob rau tib lub sijhawm, thaum cov nplais nplaum siv rau kev sib khi, kev npaj ntawm cov npoo thiab qhov huv ntawm cov nplaim yog qhov yuav tsum tau ua.
Vuam tuaj yeem tsim txoj kev sib khi zoo nrog cov khoom siv sib ze ze rau ntawm cov khoom siv niam txiv. Yas vuam txwv yog txwv rau cov thermoplastic polymers vim tias cov khoom siv thermoplastic yuav ua kom mos los ntawm cua sov. Tom qab ua kom tawv tawv, thermosetting polymers tsis tuaj yeem muag los ntawm cua kub. Piv nrog hlau, thermoplastic polymers xav tau cua sov tsawg dua rau kev vuam.
Cov txheej txheem yas vuam tuaj yeem faib ua ob pawg:
1. Mechanical mobile vuam txheej txheem: ultrasonic vuam, txhuam vuam thiab kev vuam vuam.
2. Sab nraud cua sov vuam txheej txheem: kub phaj vuam, kub roj vuam thiab cog hniav vuam.
Ultrasonic vuam
Ultrasonic vuam siv cov tshuab hluav taws xob loj ua rau kev co los ua nqaws. Cov seem yuav tsum sib dhos yog clamped nruab nrab ntawm lub vuam vij voos lub taub hau thiab lub taub hau vuam ruaj ruaj hauv qab lub siab, thiab tom qab ntawd ntawm cov ces kaum sab xis mus rau qhov chaw tiv tauj, thiab tau txais ultrasonic kev co nrog zaus ntawm 20-40KHz. Kev hloov pauv siab hloov pauv siab ua rau muaj cua sov ntawm qhov sib xyaw ua ke txhawm rau txhawm rau txhawm rau hle lub hle zoo. Cov cuab yeej siv hauv cov txheej txheem no yog kim heev, yog li nws tsim nyog siv thaum qhov ntim khoom loj.
Hom vuam no tsuas yog tsim nyog rau qhov me me uas nws qhov ntev tsis pub ntev tshaj ob peb centimeters. Cov chaw thov muaj cov vuam vuam thiab kuaj cov txheej txheem rau cov cuab yeej siv kho mob, thawv, pib seem, tshuab nqus tsev, thiab lwm yam ntawm cov tshuab ntau lub taub hau.
Txhuam Txhuam Vuam
Thermoplastic txhuam vuam (tseem hu ua" tig vuam") muaj tib lub hauv paus ntsiab lus zoo li vuam hlau. Hauv cov txheej txheem vuam no, ib qho txheej txheem yog tsau thiab lwm qhov substrate yog tig ntawm qhov kev tswj kav lub kaum. Thaum cov ntu raug nias ua ke, kev sib txhuam tsis sib xws ua rau lub polymer yaj, thiab tom qab txias, ib lub weld tsim. Lub ntsiab vuam tsis suav nrog: kev ceev nrawm, kev sib txhuam siab, forging siab, vuam lub sijhawm thiab yaj ntev.
Kev sib txhuam vuam tuaj yeem ua tau zoo vuam zoo, cov txheej txheem vuam yog yooj yim, thiab kev rov ua dua qub dua. Txawm li cas los xij, vim nws cov txheej txheem yooj yim, nws tsuas yog haum rau daim ntawv thov qhov twg tsawg kawg ib ntu yeej ncig thiab tsis tas yuav muaj kev sib dhos.
Kev co vuam
Kev co vuam tseem hu ua linear txhuam kev sib txuas. Ob qhov thermoplastic tshooj rub tawm rau txhua tus hauv qab kev tsim nyog, zaus thiab ntuag kom txog thaum muaj cua sov txaus kom cov yaj hluav taws kub yaj. Tom qab cov kev co tso tseg tsis tu ncua, feem ua ke tau sib txuas nrog txhua qhov chaw, thiab cov xim hlau polymer solidifies tsim cov weld. Kev co vuam zoo sib xws rau tig vuam, qhov sib txawv yog tias txoj kev txav yog txoj siv hloov chaw. Qhov txheej txheem vuam no yog nrawm heev, qhov nrawm zaus feem ntau yog 100 txog 240 Hz, thiab qhov dav li ntawm 1 hli txog 5 hli.
Qhov tseem ceeb dua ntawm cov txheej txheem welding no yog tias nws tuaj yeem txuas tau qhov loj thiab ua tiav ntawm cov khoom ntawm cov kab nrawm. Lwm qhov kev ua tau zoo muaj xws li: kev muaj peev xwm los txuas ntau ntu nyob rau tib lub sijhawm, cov cuab yeej vuam yog yooj yim, thiab yuav luag txhua cov ntaub ntawv thermoplastic xws li txhaj tshuaj moulded qhov chaw, qhov chaw txuas ntxiv, tshuab moulded qhov chaw, thermoformed qhov chaw, qhov chaw ua npuas thiab qhov chaw ruaj khov tuaj yeem txuas tau. Lawv tsuas yog siv hauv tsheb thiab cov khoom siv hauv tsev lag luam.
